screws for cable connections. Ensure that the cable shield is connected to the FG terminal
of the equipment.

CAUTION
• Before opening the cover, loosen the lock screw. If the screw is not loosened first, the cover
will be improperly engaged to the body, and the terminal box will require replacement. When
opening and closing the cover, remove any sand particles or dust to avoid gouging the
